Cortex X speeds up phone by 30 percent

High-performance PC SoCs too

Qualcomm introduced Prime core clocked rest from the cluster with Snapdragon 865, and Huawei had two higher clock performance cores in Kirin 990. With that in mind, ARM has introduced the Cortex-X custom program. The result is up to 30 percent peak performance compared to previous generation Cortex A77 cores.

Cortex X is a custom silicon designed on a completely different CPU architecture from Cortex, but it has a new and improved core, more insts, and Mops more NEON engines and more cache.

Chris Abernathy, distinguished engineer, Client Line of Business at ARM, was very clear as he mentioned that this core is designed for performance and short bursts of extreme performance and not for sustainable performance. The main goal is to turn the core up, get the job done, and shut it down as fast as possible to prevent unnecessary energy consumption.

Before we dig deeper, you can expect to see Cortex-X1 in future 2021 high-end smartphones - possibly late 2020 too - and PC like devices such as the next-generation 8CX from Qualcomm. Of course, ARM doesn't comment or announce products for its customers, but it is clear that the Cortex-X1 was created to pressure Intel on the notebook and foldable notebook side.

ARM came up with the Corex-X custom program, and a custom license allows partners to customize and differentiate over the standard Cortex products. The new core will follow the ARM Cortex brand, and it will only be available to Cortex-X customers.
